Procedure
4-amino-1-(2-chloro-9,10-dihydro-9,10-methanoanthracen-9-ylmethyl)piperidine (0.500 g, 1.48 mmol, prepared as described in Example 7b) was heated to 100° C. for 5 hours in 1.5 mL N-methylpyrrolidinone with 2-chloropyrimidine (0.212 g, 1.85 mmol, commercial grade purified by extraction into petroleum ether) and triethylamine (0.300 g, 29.6 mmol) under a nitrogen atmosphere. Aqueous method (3 mL, 50% v/v) was added to the warm (50° C.) reaction mixture to give a white precipitate. The solid was collected by filtration and washed with fresh aqueous methanol (5 mL, 50% v/v) to give the title compound as a white solid. The solid was dissolved in methanolic hydrogen chloride, evaporated to dryness on a rotary evaporator, redissolved in a minimum volume of fresh methanol (2 mL) and added at a slow dropwise rate to rapidly stirring ethyl ether (80 mL) to precipitate the hydrochloride salt as a white solid (0.414 g, 0.99 mmol, 67%), mp 212°-214° C.; MS(CI) 417 (M+H); NMR (250 MHz, DMSO-d6): 10.17(br s, 1H), 8.38-8.33(m, 2H), 7.67(br m, 1H), 7.52-7.49(m, 1H, 7.38-7.31(m, 3H), 7.05-6.96(m, 3H), 6.70-6.63(m, 1H), 4.47(s, 1H), 4.35-4.29(m, 2H), 4.16(br m, 1H), 3.57-3.36(m, 4H), 2.76(m, 2H), 2.12-1.90 (m, 4H).
